Definitions

  • the invention relates to a rivet holder for a rivet gun.
  • the invention also relates to a rivet gun having such a rivet holder.
  • Power tools are utilised widely for both professional/industrial and personal purposes, including in construction, gardening and around the house for the purposes of drilling, sanding, grinding, polishing for example. Power tools can vary depending on their intended use as their applications are diverse. Accordingly, power tools utilise different work members. Typically, a user using a power tool would use the power tool freely with unrestricted movement for maximum comfort and efficiency.
  • Document EP 2 502 686 A1 shows a rivet holder and a rivet gun comprising the rivet holder, and forms the basis for the preamble of claims 1 and 8.
  • Power tools are used for a wide variety of tasks and have wide-reaching application, for example in industry, construction, gardening, and housework to name a few.
  • Different types of power tools with different work members may be utilised depending on the task at hand, such as a drill, nail gun or rivet gun, etc.
  • a user of a power tool moves the power tool with the work member freely during a task.
  • Example embodiments are directed to a rivet holder.
